The circumference of a circle is 53.38 cm
What is the area in square meters? Use 3.14 for pi
I can't count lmfao
To calculate the area of a circle, you will need to use the formula A = πr², where A is the area, π is pi (approximately 3.14), and r is the radius of the circle.
First, let's find the radius of the circle using the formula C = 2πr, where C is the circumference and r is the radius.
53.38 cm = 2πr
Dividing both sides of the equation by 2π, we get:
r = 53.38 cm / (2π)
Calculating this value, we find:
r ≈ 8.5 cm
Next, let's convert the radius to meters:
8.5 cm = 8.5 / 100 m
r ≈ 0.085 m
Now we can calculate the area using the formula A = πr²:
A = 3.14 * (0.085 m)²
Calculating this value, we find:
A ≈ 0.0229 m²
Therefore, the area of the circle is approximately 0.0229 square meters.
To find the area of a circle, you need to use the formula A = π * r^2, where A represents the area and r represents the radius of the circle.
In this case, we are given the circumference of the circle, which is 53.38 cm. The formula for circumference is C = 2 * π * r.
To find the radius, rearrange the formula for circumference to solve for r: r = C / (2 * π).
Plugging in the given circumference value, we have: r = 53.38 cm / (2 * 3.14) ≈ 8.51 cm.
Now that we have the radius, we can calculate the area of the circle. Using the formula A = π * r^2 and plugging in the found radius, we have:
A = 3.14 * (8.51 cm)^2 ≈ 226.98 cm^2.
To convert the area from square centimeters to square meters, we need to divide by 10,000 (since there are 10,000 square centimeters in a square meter).
So, A = 226.98 cm^2 ÷ 10,000 ≈ 0.022698 square meters.
Therefore, the area of the given circle is approximately 0.022698 square meters.
2πr = 53.38
r = 53.38/(2π) = ....
Area = π r^2 , you have the r from above
